Question

I have an if statement in the code behind for an asp.net page, like this:

If Session("UserActiv") IsNot Nothing Then
    If Session("UserActiv").ToString() = "N" Then
        ClientScript.RegisterStartupScript(Me.GetType(),
            "Details", "LoadDetails();", True)
    End If
Else
    ClientScript.RegisterStartupScript(Me.GetType(),
        "Details", "LoadDetails();", True)
End If

If my session is not nothing, and if its N then it run the function LoadDetails()
If nothing then it also load the function, and if Y then do nothing.

Then I have the function on my main page, my only problem is, that it load the function every time I load the page, also if the session is Y, i have checked for upper Y/N and lower y/n issues and all is in UPPER case. so no problem there.

My loadDetails() function is like this:

<script language="javascript" type="text/javascript">
    function LoadDetails() {
        myModal.load();
    }

    $(document).ready(function () {

        $("#myModal").modal({
            "backdrop": "static",
            // if true, then the backdrop can be closed with a click
            // if false then there is no backdrop.
            "keyboard": false
        })

});
</script>    

I’d like this to load at page_load like now, BUT only if the session is nothing or if its N. How would I go about this?

if i do it like this, nothing happens when the session is N

Add the following sections of code to your VB.net code:

Public Function runJQueryCode(ByVal message As String) As Boolean
        Dim requestSM As ScriptManager = ScriptManager.GetCurrent(Page)
        If requestSM IsNot Nothing AndAlso requestSM.IsInAsyncPostBack Then
            ScriptManager.RegisterClientScriptBlock(Page, GetType(Page), Guid.NewGuid().ToString(), getjQueryCode(message), True)
        Else
            Page.ClientScript.RegisterClientScriptBlock(GetType(Page), Guid.NewGuid().ToString(), getjQueryCode(message), True)
        End If

        Return True
    End Function

    Private Function getjQueryCode(ByVal jsCodetoRun As String) As String
        Dim sb As New StringBuilder()
        sb.AppendLine("$(document).ready(function() {")
        sb.AppendLine(jsCodetoRun)
        sb.AppendLine(" });")

        Return sb.ToString()
    End Function

Then use:

If Session("UserActiv") IsNot Nothing Then
        If Session("UserActiv").ToString() = "N" Then
           runJQueryCode("SUCCESS!modaljquerystuff")
        End If
    Else
        runJQueryCode("FAIL!modaljquerystuff")
End If
